Patent CA-2310338-A1 (CA)
Inventor: GUNSAULIS FLOYD R
IPC: E21B10/58
Filed: 2000-05-31
Abstract: A directional boring head assembly having a directional boring head, with a deflection surface capable of steering the directional boring head, combined with a replaceable cutting member is provided. The position of the cutting member relative to the deflection surface permits the directional boring head to steer the boring machine along the desired path while providing enhanced cutting action adaptable to different soil types. As the boring machine is advanced with rotation, the leading edge of the cutting member contacts only a small portion of the perimeter of the borehole thereby increasing the contact stress between the cutting member and the face of the borehole for more aggressive cutting action in hard ground conditions. Additionally, the directional boring head is provided with a pocket adapted to conform to the cutting member. The pocket engages the cutting member so that the cutting member fits snugly within the directional boring head thereby increasing the stability of the cutting member within the directional boring head. The cutting member may be replaced to simplify maintenance and to accommodate a variety of soil conditions. The directional boring head and the cutting member function together to maximize the cutting and steering capabilities of the directional boring head assembly while maintaining the integrity of the overall structure.

Patent CA-2318983-A1 (CA)
Inventor: HO CHIH MING
IPC: B05B17/04
Filed: 1999-01-22
Abstract: An apparatus and method for forming a bubble (30) within a microchannel of a microinjector (12) to function as a valve mechanism between the chamber (14) and manifold (16), that provides for a high resistance to liquid exiting the chamber through the manifold during fluid ejection through an orifice (18) and that also provides a low resistance to refilling of liquid into the chamber after ejection of fluid and collapse of the bubble. This effectively minimizes cross talk between adjacent chambers and increases injection frequency of the microinjector. The formation of a second bubble (32) within the chamber (14) coalesces with a first formed bubble (30) between the chamber (14) and manifold (16) to abruptly terminate the ejection of fluid, thereby eliminating satellite droplets.

Title: Inhalation device for administering powdered forms of medication
Inventor: SCHWARZWALD DETLEF
IPC: A61M15/00
Filed: 1998-12-22
Abstract: An inhalation device for administering powdered forms of medication includes a housing (1) with a rotatable dosing ball (15) associated with the opening of a powder reservoir (12) located inside the housing that can be operated manually and comprises a peripheral dosing cavity (17) for receiving a portion of powder. Said dosing ball is connected with a torsion spring (16) and Further comprises a stop piece (20). In addition, it is associated with a pivotable trip flap (14) that has a movable limit stop (14a). Said dosing ball is preloaded by turning it until its stop piece comes to rest on said movable limit stop of said trip flap. It is then released as normal breathing triggers a swaying of the trip flap.      Due to a subsequent abrupt blocking of the acceleration of the dosing ball as the stop piece hits against the bottom of the housing, the medicine is catapulted out of the dosing cavity and widely dispersed in the stream of respiratory air so that it can be inhaled completely and in sync with respiration. Overdosing or release of multiple doses are excluded (Fig. 4).

IPC: C12N15/10
Filed: 1999-03-12
Abstract: A lyophilized polynucleotide composition contains at least one polynucleotide and at least one cryoprotectant, wherein the ratio of the polynucleotide to cryoprotectant is from about 0.001 to about 1.0 part by weight polynucleotide per 1.0 part by weight of the cryoprotectant. This composition also contains from about 0.5 weight percent to about (6) weight percent water, based on the total weight of the final lyophilized polynucleotide composition. The polynucleotide composition of this invention is characterized by enhanced stability, in that it retains at least 90 % supercoil over a time period of at least (10) days at a temperature of about 37 ~C. The lyophilized polynucleotide composition also has improved solubility. An improved process for lyophilization of polynucleotides employs a specific primary drying cycle, that results in the above-described stable, lyophilized polynucleotide composition.

IPC: G06F8/656
Filed: 1999-03-11
Abstract: To improve the efficiency for an update process in a software processing device with a plurality of memory partitions (4, 14), it is proposed to continue the execution of old software on original data stored in a first memory partition (4) and to update new software and related data in a second memory partition (14). In case the same state for data of old and new software is achieved (S4), an instant switch of services to the new software as far as the same state is achieved (S5) takes place.      This processing is repeated (S6) until no data to be transferred remains (S6) in the first memory partition. Thus, the present invention allows for a considerable improvement of the update efficiency with reduced disturbances during data transfer.

Patent CA-2327089-A1 (CA)
Title: Camera dolly
Inventor: CHAPMAN LEONARD T
IPC: B62D7/02
Filed: 1999-03-29
Abstract: A camera dolly (30) has a steering system (50) which provides conventional, crab, and round steering modes, selected by the operator via use of a single steering/shifting handle (44). The steering system (50) includes first (102) and second (104) transmissions and a differential (108).      Chains (80, 82, 84, 86, 88, 92, 94) link sprockets on the transmissions and differential, to steer the wheels (45) of the camera dolly to appropriate angles, so that the dolly can roll easily and without wheel scrubbing. A dolly leg position compensator (300) adjusts the amount of steering angle correction provided by the differential, to compensate for changes in the dolly wheelbase/tread dimensions. Sprockets in the differential (108) are locked intop offset positions, during conventional and round steering, to maintain proper steering angle correction, even under heavy loads. Active idlers (75, 76, 77, 99) are mechanically linked within the steering system to automatically maintain appropriate chain tension, in all steering modes.

Patent CA-2331270-A1 (CA)
Inventor: COOPE ROBIN JOHN NOEL
IPC: G02F1/1685
Filed: 1999-08-06
Abstract: L'invention concerne un dispositif d'écran et un procédé dans lesquels l'électrophorèse et/ou des surfaces prismatiques doubles servent à contrecarrer de façon régulable la réflexion interne totale au niveau d'une interface entre des matériaux présentant différents indices de réfraction. Dans un mode de réalisation, un milieu électrophorétique (26), tel que de l'acétonitrile, entoure un réseau de fibres légères diélectriques solides (20A, 20B, 20C). En l'absence d'activité électrophorétique, les fibres réfléchissent de façon interne et totale la lumière qui passe dans lesdites fibres tandis qu'un réflecteur (22) renvoie la lumière afin qu'elle soit émise de façon diffuse à travers les extrémités des fibres (24). En revanche, si les fibres sont soumises à une activité électrophorétique, leur capacité réflexion interne totale est contrecarrée. Dans un second mode de réalisation, la lumière est redirigée à travers deux surfaces prismatiques (30, 32) de sorte que le phénomène de réflexion interne totale puisse se produire et être contrôlé au niveau d'une surface plate (38). Dans un second mode de réalisation, on utilise à la fois l'électrophorèse et des surfaces prismatiques doubles (52, 54) pour pouvoir contrôler sans entrefer le phénomène de réflexion interne totale au niveau d'une surface plate (58).

Title: Deep desulfurization of fcc gasoline at low temperatures to maximize octane-barrel value
Inventor: SHIH STUART SHAN-SAN
IPC: C10L10/10
Filed: 1999-10-25
Abstract: Low sulfur gasoline of relatively high octane-barrel value is produced from cracked, sulfur containing olefinic naphtas by hydrodesulfurization at low temperature and low space velocity over either a conventional catalyst, such as CoMo/Al2O3, or a dual functional catalyst, such as CoMo ZSM-5/Al2O3. This approach also minimizes the olefins/hydrogen sulfide re-combination frequently observed at high temperature. The process produces a gasoline having a reduced sulfur content with a less than 5 % change in motor octane number and a less than 10 % change in research octane number.
